There is an API endpoint for starting all roles on a host: https://archive.cloudera.com/cm7/7.2.4/generic/jar/cm_api/apidocs/resource_ClouderaManagerResource.html#resource_ClouderaManagerResource_ClouderaManagerResourceV41_hostsStartRolesCommand_POST For stopping all roles on a host, you have to iterate in your script/code over all role instances deployed on the host, and stop them one after the other.

Hi Matt, assuming you want to enable external authentication to LDAP in Cloudera Manager. Please find steps in the product documentation here for 6.x and here for 7.x The steps you listed seem about right and should work. I suggest to verify if CM makes use of this JDK in the CM -> Support -> About page, and if necessary follow the steps in documentation to explicitly set the -Djavax.net.ssl.trustStore and -Djavax.net.ssl.trustStorePassword startup properties.

There are several options for you here, you have to pick one that best matches your requirements. If you are looking to backup your HDFS data but don't have capacity for a DR cluster, then backup to AWS S3 may be an option for you. Requires a cluster upgrade to later 5.x version, though, as this option is not there on 5.4 version. Besides that, if you are able to completely restore the cluster nodes from your filesystem backups then you will be able to restore your HDFS data.

Try something like # curl -u admin "http://$cmhost:7180/api/v33/clusters/Cluster%201/services/IMPALA-1/impalaQueries?filter=(query_state=RUNNING%20and%20query_duration>=1000)&from=2021-05-04T00:00:00.00Z"

Great to hear @SuryaDilip ! Although I noticed my last update was not complete, I referenced the CM -> Administration -> Settings -> Category: Ports and Addresses -> Cloudera Manager Hostname Override configuration property.

I did a trial installation using cloudera-manager-installer.bin. I have been looking for a solution of this problem for weeks now, without being able to find one. Any ideas on how i can resolve this?

The clean and recommended way is to stop those services which are affected, before the backend database is shut down for maintenance (e.g. during maintenance window).

In CM you can also go to CM -> HDFS -> Click on active "Namenode" link -> Open "Actions" dropdown -> Select "Refresh node list"
